A cylindrical lock with a latch bolt, including an electro-mechanical mechanism enabling pull-back of the latch bolt to a retracted position. In an exemplary embodiment, the electro-mechanical mechanism includes an electrically powered motor and a drive linkage system coupling the motor to the latch bolt, the electro-mechanical mechanism configured to fit within a cylindrical hole formed in a door.

A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

A closure system for a vehicle comprises: a dual-hinge closure comprising a first portion hinged to the vehicle by a first hinge, and a second portion hinged to the first portion by a second hinge; a frame that at least in part surrounds an opening in the vehicle; an adjustable bump stop subassembly mounted to the first portion, wherein the adjustable bump stop subassembly rests on the frame when the first portion is in a closed position; and a latch system comprising a latch configured to engage a horizontal striker, the latch system configured so that an end of the second portion opposite the second hinge latches to and unlatches from a distal portion of the frame by essentially horizontal motion.

A door opening prevention mechanism includes a lever member rotatable relative to a base member and swingable in a vehicle inside-and-outside direction, and an urging member to bias the lever member toward a set position. The lever member is held in the set position when an outer handle is located in a door closing position when a given inertial force does not act in a vehicle outside direction during a vehicle collision, and swings in the vehicle outside direction from the set position to be moved to a locked position against an urging force of the urging member when the inertial force acts. When the lever member is in the set position, movement of a connection lever in a door opening direction is allowed. When the lever member is located in the locked position, movement of the connection lever in the door opening direction is restricted.

A door lock for a handle, comprises a housing, a rotatable connector inside the housing, a first elastic element and a second elastic element both arranged inside the housing. The rotatable connector is interacted with the handle. The first elastic element is at least configured to provide a restoring force for the handle to return to its origin position when the handle is rotated upward to lock the door, and the second elastic element is configured to provide a restoring force for the handle to return to its origin position when the handle is rotated downward to unlock and open the door, as well as to provide enough resistance to remain handle at its origin position when the handle is released. The door lock is effort-saving for the users to rotate the handle upward, and also adapted for various handles having different weights, to be remained at the origin position when the handle is released.

A locking device for fixing an electronic component to a housing includes a rear stop frame adapted to be disposed on the housing for fixing a rear side of the electronic component, a front frame spaced apart from and in front of the rear stop frame and having a retaining portion, and a locking mechanism including a positioning frame for fixing a front side of the electronic component, and a locking member disposed on the positioning frame and releasably engaged to the retaining portion. The locking member is engaged to the retaining portion to fix the positioning frame on the front frame.

A fastener for highly curved access panels on aircraft or other structures, featuring a bottom-grasping design allowing for an unblemished outer panel surface, simple and rapid pneumatic fastener actuation, built-in clamping pre-load, and full retractability of the fastener inside the supporting structure. The fastener includes a Belleville spring with a piston centrally disposed therein, where the piston and spring deflect outward upon application of pneumatic pressure. A pressure chamber within the piston has inlet and outlet orifices designed so that the pressure in the piston chamber gradually increases, requiring several seconds to reach a pressure which causes locking dogs in the piston to deploy radially into a cavity in the access panel. When pressure is removed, the Belleville spring relaxes, the locking dogs grasp a lip of the cavity, and the access panel is latched onto the structure with a clamping pre-load. A pneumatic sequence for unlatching is also provided.

The invention relates to a door lock provided with an oblique bolt. The objective is to decrease the external force directed into to deadlocking organs. The oblique bolt consists of slanted surfaces on both sides such that the tip part is narrower at its tip than in the back part of the tip part. The tip part has recesses in its lower part and upper part, which extend from the tip to the back part. Both recesses have a turning piece. Additionally, the oblique bolt has a support piece and flexing organs. The turning pieces guide external force up to a given turning angle via the support piece and flexing organs into the deadlocking organs.

Disclosed embodiments relate to a cable cover to be attached thereto or detached therefrom using a spring, thereby including an effect of facilitating the attachment and detachment of the cable cover through an elastic force of the spring.

An aircraft overhead stowage system for a cross-aisle galley complex. The aircraft overhead stowage system includes a stowage compartment housing disposed above a ceiling of the galley complex that is supported above the ceiling by a stowage support structure. A first stowage compartment and a second stowage compartment are each movably engaged with and disposed inside the stowage compartment housing, and each stowage compartment is movable between a stowed position and a deployed position relative to the stowage compartment housing using a vacuum system. A vacuum generator that creates a vacuum force is mounted on the stowage compartment housing, and a plurality of vacuum bellows connected to each stowage compartment are in fluid communication with the vacuum generator. The vacuum system causes the stowage compartments to move between the stowed position and the deployed position. Vacuum-driven and manually-driven latching assemblies and removable extensions for each stowage compartment are also provided.
